[Feature Request] "Save" button in playback control

[danielmmmm]

The playback control is very useful, but it is missing the possibility to save the recording to a (wav) file.

(Also, thanks for making this wonderful audio tool!)

@celeste-sinead built the playback control, she could add this easily

Yeah it's something I also want so it'll probably happen eventually. It also shouldn't be terribly difficult for anyone to jump in and do.
